RDMA/hns: Fix QP's resp incomplete assignment
The resp passed to the user space represents the enable flag of qp,
incomplete assignment will cause some features of the user space to be
disabled.
Fixes: 90ae0b57e4a5 ("RDMA/hns: Combine enable flags of qp")
Fixes: aba457ca890c ("RDMA/hns: Support owner mode doorbell")
